Said machine is adapted to trim the-top lift so to 'shape'called for..

1 'Only such parts ofthe are shown that my improvements cooperate with. )The;

generalconstruction and arrangement ofsuch I machines are {not changedg'therefdre i it;v was f nottho'ught necessary toushow or describe 5 'those parts- -Oneof the main improvements herein is thatuwhich :allows ,thet-trimminfg 'head,with its; various adjustments, to be I moved concentricallyfabout thetriinmer axis. a j I thus permitting any angle that may be desired by moving the head to the desired po ition.

'ming' machine is illustrated, The imaingshaft 11 1*is housed in1-suitablebearings 12713, having a drivepulley 14; ;The1outer end ot fl said shaft maybe provided witha hand wheel or other means for turning the shaft 11. 1 0

the other or free end of said shaft is secured '7 thetrimmer orcutter 15; being of. such size and shape as "to perform the necessary-work on thetop lift 16,;as it-is'presentedthereto. 1

The bearing 13" has an extended hub (not -shown) gonwhich is 'mounted'the adjustable guard block and bracket 17; .andheldgin-propthereto; Fig. 2 is an 'enlargeddetail 'iervworking relation tothetrimmerby reason give then-particular a I of the adjusting screw 18. i The adjusting tothetrimmer.' I v ,The bifurcated guard arm 22 is hinged at screw 19 adjusts the relation of the guard 'block arm 20 so that the guard and trimmer are always in proper relation to each other. The knurledheaded screw 21 regulates the position of the guard verticallywith relation its upperend to the arm 20 by a screw, 23.

The lower P ihearmcar ies the urv d guard 24 that houses the trimmer, the upper part thereof fitting the enlargedcurved part of the arm 22, and is secured theretoby'means of screws 25. Said guarimayfprm apart of a perfect sphere, except at its lowermost point 26, which is skived so as. to .allow the trimmer togetcloseto the heel. The guard 24. is'held in operating position to the trimmer by reason of thespring 27, whilethe screw" 28 holds the same in proper position. Thus it'lwill be seen that once: the guard; is

adjusted to the trimmer, itoperates always 7 about the-axisof the same, Which'is a decided advantage for any operation on the heel, be

it'curved or straight. In addition to theabove it not onl' serve's as'a guide for the work but protects t e same, alsotheoperator from contact with the-cutteraccidentally or otherwise.

i Referringnow toFig. 2, it will be seen that the platform 29 is provided with anadjust-.

able guard plate 30,: held in properv position with relation-to the trimmer by'screw. 81,

while to the sideof said platform is another adjustable sliding plate 32, a knurled nut 33, giving the proper adjustment thereto. the upper part of plate 82 issecured an ad:

justable trimming'knife84. Thelplatformis I so positionedas torock on ao'radiusifrom the cutting point of the trimmer, thuskeeping the trimmer guard plate 80 always in relation to each, other, irrespective of other adjustmentsthat mayhave been'made.

In the ffoperation off the machine, each designed heel is provided with its proper size top lift 16" that has'to be shaped to that particular styleheel: In Fig. 8 ,-a portion of 1 aheel is shownwith the top -liftl6 inposi- J tion for the operator to place the same against theplatform 29' and guard plate 30. He moves the sameupwardly' till the guard 24; is reached, the trimmer starts: cutting the outer. edge tothe shape of the heel, and then i The turns'the'same around. so as to trim the breast as well by reason of the guard being curved as shown, the-operator is, enabledvto cause the lift to be entirely trimmed, as has been pointed out. After the edge trimmer .fhas completed the edge, the liftispcomplete without the necessity of further. cutting or -tr1mm1ng..:- The lift: is then ready for the bur'nisher to finish in thezparticular style.

Here is where the decided I advantage accrues, reason ofthe operator being ableoto trim the whole top lift 16 byimachine instead of only, partially, and requiring. additional manual labor before the same becomes a finished product.

Referring to Fig. 5, it will be seen that I mount upon the adjustable slide 82 a knife 85,which is held to said slide 32 by screw 36. This not only gives an adjustment to the knife 35, to trim any, lift, be it 5 or inch thick, but the knife, by reason of its vertical adjustment and its angular adjustment, may be made to operate on any lift presented.

This applies tothe curved as well as the straightbreastheels. Again, by reason of its angular adjustment, it is adapted to give that slight bevel cut tothe outer edge of the lift that is desired to complete the work on the lift; As thetrimmer cutsthe lift andas the operator turns the same around, the shaggy edge. contacts with the knife 35, and'is per.- fectly and completely trimmed.

It will be apparent'with reference to Figs. 3 and 1-, that it is a simple operation to trim the. outer edges of the lift, it beingonly necessary to keepfthe same in contact with the guard and turning the, same around as fast as the trimmer cuts. -The, trimmer under the guard shown in Fig. 3is adapted to trim any size top lift of any shape, whilethe trimmer under the guard shown in Fig. l, which is given the same, reference character only pruned, is adapted to trim the outer edge of any lift, and the straight breast of the heel,

but. is of no use on curved breasts. While this latter designed guardissuperior to any known, for its work andthe protection afforded, yet it can only operate on heels as described; 7

Referring to, the modification shown in Fig. 7 it. \vil-lbe observedthat the guard 24,. is the same as that shownin Figs. 1, 2, 8 and 6, with only the exception that the same is cut away as at 37. This permits the operator to seezat all times the operations being performed on thelift, viz, the trimming and the final operation by the knife 85, with all the other advantages.

'As has been noted, the guard carrying bracket is adjustable about the aXisof the trimmer, while the guard itself is adjustably secured thereon to bemoved towards or. from the trimmer, or may be raised or lowered with ments forin substituting parts to finish particular heel, to meet the necessary specifica tions. Means have been provided for hold- .ing the heel ina positionwhile a trimmer has taken off the outer edge or on straight breast 1 of heels; but inthis device'it is necessary for adjustment, said slide being adjustable in.

either direction toor awayfrom thetop lift, according to the thickness; In the operation of this machine, a curved'breast cannot be accomplished thereon without additional .manuallabor. f

While I have herein described the form of my invention as at present preferred:v and which I consider to represent the best em bodiment thereof, yet I desire to have it understood that the various forms shown are only illustrative and that the invention may be carried outin other ways thanthatshown and described; for instance, the arrangement of the guard may be cut out on each side of a central guard covering the trimmer and leava F slide,'fwhereby the" ed trimmed of any j thereon;

ing its lower edges with the curve, as shown, or the curved lower part of the'g'uard may have only short extending arms on each-side of the central guard section, as may bedesired,- or the curved guard may be providedwith itslower edges curved, more or: less ex tended. Any of the forms may be used or any modifications thereofto advantage, andthey are all intended to comewithin'thescope of Y the claims.
